The Jodi Arias murder trial is set to resume in Arizona on Monday with the defense calling their psychologist to the stand again.

Arias concluded her 18th day of testimony last week. On Thursday the defense called their next witness, mental health expert Richard Samuels.

Samuels testified about Arias' mental state before and after the June 2008 shooting, stabbing and slashing of Travis Alexander. Arias, 32, is charged with first-degree murder and faces the death penalty if convicted.

“She was not able to tell her family about what happened," Samuels said. "She was not able to tell anybody about what happened. And this is a classic symptom of an acute stress disorder.” That disorder developed into post-traumatic stress disorder, or PTSD, he said.

Arias told jurors she killed Alexander in self-defense after he attacked her for dropping his camera. Prosecutors say the murder was premeditated and fueled by jealously.

The trial is set to resume at about 2:00 p.m. Eastern time, when Samuels is expected to resume his testimony.

Foggy Memories

"With regard to these photographs ... she was not suffering any of these foggy memories, was she," Martinez asked.

"The foggy memory occurred at the time of the killing," Samuels replied.

The trial of Jodi Ann Arias, which began Jan. 2, is one of the biggest court proceedings to take place since Casey Anthony was acquitted of murdering her child.
The 32-year-old photographer is accused of shooting her lover, Travis Alexander, in the face, stabbing him 27 times and slitting his throat from ear to ear in the shower of his Mesa, Ariz., apartment.
The case, which has been more than four years in the making, has routinely captured headlines around the world, especially as the details became public.
